Problems solved by technology

The disadvantage of this solution is: due to structural limitations, the first air duct needs to cool components such as the inverter and flywheel first, resulting in poor cooling effect on the engine and muffler.
However, there is no corresponding disclosure about a technical solution for a layout with small volume, light weight and good cooling effect.
[0006] To sum up, there is an urgent need for a layout method of the air duct cooling frequency conversion machine with small size, light weight and good cooling effect, but there is no report about this air duct cooling frequency conversion unit.

Abstract

The invention relates to an air duct type cooling frequency conversion unit and a layout method thereof. The layout mode of the air duct type cooling frequency conversion unit involves a first air duct and a second air duct. The air flows into a power generator via a first air inlet from the first air duct, enters an engine after cooling the power generator, then cools the engine, enters a silencer after cooling the engine, and is discharged outwards after cooling the silencer. And the air flows in via a second air inlet from the second air duct, passes through a cooling inverter and then is converged with the first air duct to flow out at the silencer. The layout method of the air duct type cooling frequency conversion unit has the advantages that the whole machine is made small in size, low in weight and good in cooling effect through the improvement of the whole machine structure and the cooling layout of the air ducts.

Description

technical field [0001] The invention relates to the technical field of frequency conversion units, in particular to an air duct cooling frequency conversion unit and its layout method. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards; as a kind of emergency power supply - variable frequency generators are becoming more and more popular. However, there are following defects and deficiencies in the frequency conversion generator in the prior art: [0003] First of all, regarding the structure, in the frequency conversion generator set in the prior art, the generator is installed below the muffler. The inverter is installed at the outer end. In order to ensure the stability of the engine speed and achieve the purpose of controlling the smooth operation of the engine, the flywheel is made of cast iron in a solid disc shape, which makes the size of the flywheel larger, the size of the whole machine is large...
